If your Lenovo NM-A481 laptop is only charging when turned off, the issue could be related to power management settings or a hardware problem. Possible solutions include disabling Fast Startup, checking for power-off charging settings, and verifying the charging port and cable.

Here's a more detailed breakdown:
1. Check Power Management Settings:

• Fast Startup:
  If Fast Startup is enabled, it might prevent the laptop from fully charging when it's in a sleep state, even with the charger plugged in.
  • To disable Fast Startup: Go to System and Security > Power Options > Choose what the power buttons do > Change settings that are currently unavailable > Shutdown settings.
• Power-off Charging:
  Some laptops have an option to charge the battery when the device is completely powered off. Check if this setting is enabled in your BIOS or power settings.

2. Verify the Charging Port and Cable:

• Inspect the charging port:
  Look for any debris or damage in the port. You might need to use a toothpick or compressed air to remove any blockages.
• Test with a different charger:
  If the issue persists, try using a different charger or cable to rule out a problem with the charger itself.
• Check for loose connections:
  Ensure the charger is securely plugged into the laptop and the wall outlet.

3. Check the BIOS:

• Access the BIOS:
  Shut down the laptop, press the Novo button (or the F2/Del key during startup), and select BIOS Setup.
• Check for charging settings:
  Some BIOS configurations allow you to control charging options, such as enabling or disabling charging when the laptop is powered off.
